WinterWarm Fireplace Insert or System
Adjust the Damper as Needed
Examine your WinterWarm’s damper after the first 50 hours of use and adjust it if necessary. Thereafter, check the damper at least once a year and adjust as needed.
Both fine and coarse adjustments to the damper are possible. Begin with the fine adjustment, which modifies the pressure on the damper plate directly; it will take care of most sealing problems. Proceed to the coarse adjustment, which adjusts the pressure at the damper latch, only if you cannot achieve a satisfactory seal with the fine adjustment.
To inspect how well the damper seals, first make sure that the fire is out and that the WinterWarm is cool. Open the front door, and close and lock the damper. Visually inspect the seal between the damper plate and the damper frame; there should be no gaps. Now, push gently on the damper — there should be some give, but no rattle. If there is a gap in the seal or a rattle, adjust the damper.

Care of the Catalytic Combustor
This wood heater contains a catalytic combustor, which needs regular inspection and periodic replacement for proper operation. It is against the law in the United States to operate this wood heater in a manner incon- sistent with operating instructions in this manual, or if the catalytic element is deactivated or removed.
Under normal operating conditions, the catalytic com- bustor should remain active for two to six years (de- pending on the amount of wood burned). However, it is important to monitor the combustor periodically to ensure that it is functioning properly, as well as to de- termine when it needs to be replaced. A
The combustor should be visually inspected “in place” for fly ash accumulation and physical damage three times per year. Actual removal of the combustor is not recommended unless a more detailed inspection is war- ranted because of diminished performance as outlined below.
The refractory package that houses the catalytic com- bustor should be inspected annually for a
The catalytic combustion system includes an air supply for secondary combustion. The probe which controls the supply should also be inspected annually.
